A Hydrogen‐Bonded Organic Framework (HOF) with Type IV NH₃Adsorption Behavior

This is the authors' abstract. We don't add key points for this paper.

An S‐shaped gas isotherm pattern displays high working capacity in pressure‐swing adsorption cycle, as established for CO 2 , CH 4 , acetylene, and CO. However, to our knowledge, this type of adsorption behavior has not been revealed for NH 3 gas. Herein, we design and characterize a hydrogen‐bonded organic framework (HOF) that can adsorb NH 3 uniquely in an S‐shape (type IV) fashion. While conventional porous materials, mostly with type I NH 3 adsorption behavior, require relatively high regeneration temperature, this platform which has significant working capacity is easily regenerated and recyclable at room temperature.
